Description

Technical Field

[0001] The present invention belongs to the technical field of geological drilling equipment, and specifically relates to a geological drilling equipment with a drilling buffer and correction function. Background Art

[0002] Geological drilling equipment is a special mechanical equipment used in the process of geological exploration to drive the drill tool to drill physical geological data (such as core, ore core, cuttings, liquid sample, gas sample, etc.) from the ground. The main types include rotary drilling rigs, percussion drilling rigs, in-situ drilling rigs, and core drilling rigs. In addition, according to factors such as drilling depth, purpose, and construction site, geological drilling equipment can be further subdivided. For example, according to drilling depth, it can be divided into surface sampling machines, shallow hole drilling rigs, medium-depth hole drilling rigs, deep hole drilling rigs, and ultra-deep hole drilling rigs; according to purpose, it can be divided into hydrogeological water well drilling rigs, oil drilling rigs, etc.; according to construction site, it can be divided into surface drilling rigs, tunnel drilling rigs, subsea submerged drilling rigs, etc.

[0003] When the current drilling device drills into the rock formation, it mainly drives the drill pipe and the drill bit to rotate as a whole through the driving device. Due to the different strengths of different rock formations, the force on the drill bit will be different, which will cause the drill bit and the drill pipe to deviate. Therefore, a buffer correction component is required. The sensor is used to judge the deviation and then push for reset. This method corrects the motor rotor and the drill pipe. However, since the force is on the drill bit part, long-term deviation correction will cause the connection part between the drill bit and the drill pipe to tilt, damage, and loosen, reducing the service life. Therefore, it needs to be improved. Summary of the Invention

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Such as Figures 1 to 12As shown in the figure, the present invention provides a geological drilling device with a drilling buffering and correction function, including a drilling machine body 1, and further including: a support frame 3, the support frame 3 is arranged on one side of the top end of the drilling machine body 1; a drilling driving device 4, the drilling driving device 4 is slidably installed on one side of the support frame 3; a fixed sleeve 5, the fixed sleeve 5 is arranged at the bottom of the drilling driving device 4; a drilling assembly 6, the drilling assembly 6 is arranged at the bottom of the output end of the drilling driving device 4; a buffering and correction mechanism 7, the buffering and correction mechanism 7 is arranged at the bottom of the fixed sleeve 5; wherein, the buffering and correction mechanism 7 includes an arc block 701 movably installed at the bottom of the fixed sleeve 5, an outer end of the inside of the arc block 701 is movably installed with a movable block 702, a second ball screw 12 is arranged on the outside of the arc block 701, an inner end of the arc block 701 is provided with a limiting member 703 movably installed inside the fixed sleeve 5, an oil delivery assembly 704 located at the inner end of the movable block 702 is arranged inside the arc block 701, an inner end of the limiting member 703 is provided with a limiting rod 705 located inside the limiting member 703, and the corresponding limiting rods 705 are communicated through an oil passing assembly 13.

[0022] When the limiting rod 705 at a certain position is subjected to the force generated by the offset of the drilling assembly 6, the lubricating oil inside the limiting rod 705 will be introduced into the corresponding limiting rod 705 through the oil passing assembly 13, so that the hydraulic pressure at the other end becomes larger, and the forces received by both ends are balanced, so that the forces received by the drilling part of the drilling assembly 6 are balanced, and buffering and correction can be assisted.

[0023] As Figure 1 shown, a fixing mechanism 2 is arranged on the outer end of the drilling machine body 1, and the number of the fixing mechanisms 2 is four.

[0024] Adopting the above scheme: Through the design of the four drilling driving devices 4, the drilling machine body 1 can be assisted in supporting and fixing when it moves to the designated drilling position.

[0025] As Figure 3 shown, the drilling assembly 6 includes a drill pipe 601 and a drill bit 602; The drill pipe 601 is fixedly installed at the bottom of the output end of the drilling driving device 4, and the drill bit 602 is threadedly sleeved at the bottom of the drill pipe 601.

[0026] Adopting the above scheme: By providing the drill bit 602, the size of the drill bit 602 is not fixed, and it can be replaced with a corresponding size according to different drilling conditions.

[0027] As Figure 3 shown, a sealing ring 14 located above the drill bit 602 is arranged on the inner wall of the fixed sleeve 5, and the sealing ring 14 is made of ethylene propylene diene monomer rubber.

[0028] Adopting the above solution: Since ethylene propylene diene monomer (EPDM) rubber has good wear resistance and weather resistance and can maintain its elastic properties within a wide temperature range, when the drill bit 602 and the drill pipe 601 rotate and deflect as a whole and generate high temperatures, the sealing effect between the fixed sleeve 5 and the drill pipe 601 can still be maintained.

[0029] As Figure 7 shown, the oil delivery assembly 704 includes an oil delivery cylinder 7041, a first piston rod 7042, and an oil delivery pipe 7043; The oil delivery cylinder 7041 is fixedly installed inside the arc block 701. The first piston rod 7042 is movably installed at both ends of the inner cavity of the oil delivery cylinder 7041. The outer end of the oil delivery pipe 7043 is fixedly connected to the inner end of the movable block 702. The inner end of the oil delivery cylinder 7041 is internally connected to the inside of the limiting rod 705 through the oil delivery pipe 7043.

[0030] Adopting the above solution: By providing the first piston rod 7042, when the movable block 702 moves towards or away from each other, the first piston rod 7042 will drive the hydraulic oil inside the oil delivery cylinder 7041 to be introduced into the limiting rod 705 through the oil delivery pipe 7043 or draw out the hydraulic oil in the inner cavity of the limiting rod 705.

[0031] As Figure 7 shown, the limiting rod 705 includes a buffer correction contact rod 7051, a second piston rod 7052, a first spring 7053, and a first one-way valve flap 7054; The second piston rod 7052 is arranged in the middle of the inner end of the arc block 701. The buffer correction contact rod 7051 is movably installed at the inner end of the second piston rod 7052. The second piston rod 7052 is elastically connected to the inner cavity of the buffer correction contact rod 7051 through the first spring 7053. The first one-way valve flap 7054 is arranged at the inner end of the inner cavity of the second piston rod 7052. The inner end of the buffer correction contact rod 7051 is slidably connected to the inner wall of the drill pipe 601 through a first sliding groove 8 opened at the outer end of the drill pipe 601.

[0032] Adopting the above solution: Through the elastic force design of the first spring 7053, the movement of the buffer correction contact rod 7051 due to the pressure it receives can be buffered, greatly reducing the pressure on the buffer correction contact rod 7051 and reducing damage.

[0033] As Figure 10 shown, a limiting component 9 is arranged inside the arc block 701 and is located outside the inner end of the movable block 702. The limiting component 9 includes a sliding groove 901, a sliding block 902, a limiting shaft 903, and a second spring 904; The sliding groove 901 is fixedly installed inside the arc block 701. The sliding block 902 is arranged on the outer side of the inner end of the movable block 702. The limiting shaft 903 is arranged inside the top sliding groove 901. The outer side of the top part of the sliding block 902 is elastically connected to the inner wall of the sliding groove 901 through the second spring 904.

[0034] Adopting the above scheme: By arranging the second spring 904, when the second spring 904 is in a stretched state, when the whole arc block 701 needs to move outward for adjustment, the pulling force of the second spring 904 will be released, thereby pulling the sliding block 902 and the movable block 702 to extend outward.

[0035] As Figure 12 shown, a synchronization component 10 is arranged on the top of the arc block 701. The synchronization component 10 includes a mounting shaft 101, a synchronization rotating plate 102 and a fixed block 103. The mounting shaft 101 is arranged inside the top of the arc block 701. The synchronization rotating plate 102 is movably sleeved on the top of the mounting shaft 101. The fixed block 103 is arranged on the top of the top sliding block 902. The bottom ends of both sides of the synchronization rotating plate 102 are slidably connected to the inside of the fixed block 103.

[0036] Adopting the above scheme: By arranging the synchronization rotating plate 102, through the limitation of the mounting shaft 101 and the synchronization rotating plate 102, the telescopic movements of the two fixed blocks 103, the sliding block 902 and the movable block 702 can be kept at the same distance.

[0037] As Figure 4 shown, a positioning component 11 is arranged at the bottom of the arc block 701. The positioning component 11 includes a connecting block 1101, a second sliding groove 1102 and a first ball screw 1103. The connecting block 1101 is fixedly installed at the bottom of the arc block 701. The second sliding groove 1102 is opened at the top of the drill bit 602. The first ball screw 1103 is designed at the bottom of the connecting block 1101. The first ball screw 1103 is slidably connected to the inside of the second sliding groove 1102.

[0038] Adopting the above scheme: When the position of the second sliding groove 1102 at the top of the drill pipe 601 with different sizes changes, the first ball screw 1103 and the whole connecting block 1101 can move synchronously, thereby limiting the position of the whole arc block 701 during movement.

[0039] As Figure 5 shown, the oil passing component 13 includes a delivery pipe 1301 and a second check valve flap 1302. The delivery pipe 1301 connects two corresponding buffer correction contact rods 7051. The second check valve flap 1302 is arranged at the end of the delivery pipe 1301.

[0040] Adopting the above solution: By providing a delivery pipe 1301, when there is movement inside the buffer correction contact rod 7051, the internal hydraulic oil will enter the delivery pipe 1301 and respectively push open two second one-way valve flaps 1302 and introduce them into the corresponding limiting rod 705. The material of the delivery pipe 1301 is not fixed and can be designed according to the actual situation to avoid affecting the movement of the buffer correction contact rod 7051.

[0041] The working principle and usage process of the present invention: First, when installing drill bits 602 of different sizes, the entire movable arc block 701, connecting block 1101, and first ball screw 1103 can be moved until the first ball screw 1103 is smoothly inserted into the second chute 1102 at the top of the drill bit 602 of the corresponding size. When the arc block 701 moves, it will squeeze the movable block 702 to retract or pull the sliding block 902 and the movable block 702 to extend by the second spring 904. As a result, the first piston rod 7042 slides on the inner wall of the oil delivery cylinder 7041, causing the oil delivery cylinder 7041 to drive the first one-way valve flap 7054 to open through the first piston rod 7042. Then, the inner cavity of the oil delivery cylinder 7041 will draw away the hydraulic oil in the inner cavity of the buffer correction contact rod 7051 or introduce the internal hydraulic oil into the buffer correction contact rod 7051 through the oil delivery pipe 7043, enabling the second piston rod 7052 to move smoothly.

[0042] When the movable block 702 undergoes telescopic movement, it will cause the fixed blocks 103 to move towards or away from each other. At this time, the two end portions on both sides of the synchronous rotating plate 102 will slide along the inside of the fixed blocks 103, causing the synchronous rotating plate 102 to rotate. Due to the limiting effect of the mounting shaft 101, the synchronous rotating plate 102 can rotate around the center of the mounting shaft 101 to limit the same-distance telescopic movement of the two fixed blocks 103, the sliding block 902, and the movable block 702.

[0043] Subsequently, when the operator controls the overall movement of the drilling body 1 to a designated position for drilling, the fixing mechanism 2 can then be controlled to position and fix the entire drilling body 1. Then, the support frame 3 is controlled to drive the entire drilling drive device 4 to move downward, and when the drilling drive device 4 is started to drive the entire drill pipe 601 and drill bit 602 to rotate, the drill bit 602 can smoothly drill the rock formation. When drilling into rock formations of different strengths, a huge pressure will be encountered on one side of the drill bit 602, causing the entire drill bit 602 and drill pipe 601 to tilt, so that the buffer correction contact rod 7051 is squeezed and moved. The hydraulic oil inside the buffer correction contact rod 7051 is squeezed by the second piston rod 7052 and enters the delivery pipe 1301 to push the second one-way valve flap 1302 to open. Finally, the hydraulic oil is introduced into the buffer correction contact rod 7051 at the corresponding end through the delivery pipe 1301, increasing the pressure of the buffer correction contact rod 7051 at the corresponding end, so that the pressures received by the buffer correction contact rods 7051 at both ends are balanced. And the pressure received by the buffer correction contact rod 7051 can be buffered by the first spring 7053. Finally, the received pressure is balanced, and the entire drill bit 602 and drill pipe 601 are successfully corrected.
